Courteney Cox: David Arquette 'Is My Best Friend'

“He’s my favorite person in the world,” Courteney Cox told PEOPLE of her estranged husband David Arquette at the Cougar Town TCA party. “He’s my best friend. No matter what happens in our future, he’s my very best friend.”

Cox tells PEOPLE, “We sold one show, Ten Year, about a couple who separated after 10 years of marriage. It’s not really about David and me, but it’s something we related to and we thought we should tell a story about people who could actually get along after being separated. It’s telling a different version.”
